Alright I've got a few questions about calcium and all that with these chemicals I'm starting to add. The other day I picked up some C-Balance 2 part buffer and calcium stuff. It says add a teaspoon per 20 gallons of each one in even parts, so I did that today, But my test 5 minutes ago is saying my calcium is down to 195, and it was 225 2 days ago. I added 2 teasepoons of each part A and B today and also added iodine yesterday (which is supposed to only be 2 drops once a week) I dont have an iodine test? If that exists but ill stick to 2 drops a week like it says. Why would my calcium be falling? I added some saltwater today because i want to work my salinity up to a normal level (where everone else keeps theirs, but the LFS guy is telling me to keep it at about 1.021 which was way low compared to foster and smiths water @ 1.0255. Would my clam have ate up that much calcium in 2 days? even after adding my new chemicals? Or is this instant ocean calcium test garbage? It was one of the more expensive ones, but the lady recommended it.
